Definition of vein
i. An epigenetic mineral filling of a fault or other fracture in a host rock, in tabular or sheetlike form, often with associated replacement of the host rock; a mineral deposit of this form and origin.
See Also: true vein
Compare with: lode
ii. A narrow waterway or channel in rock or earth. Also, a stream of water flowing in such a channel.
Ref: AGI
iii. A thin, sheetlike igneous intrusion into a fissure. Not recommended usage.
Ref: AGI
iv. A coal seam or a bed of slate or other rock. Not recommended usage.
Ref: BS, 11
v. A zone or belt of mineralized rock lying within boundaries clearly separating it from neighboring rock. It includes all deposits of mineral matter found through a mineralized zone or belt coming from the same source, impressed with the same forms and appearing to have been created by the same processes.
Ref: Ricketts
vi. A mineral deposit, usually steeply inclined. Used to describe a body that is usually smaller and has better defined walls than a lode.
Ref: Nelson
vii. A rock fissure filled by intruded mineral matter. Many valuable minerals are codeposited with gangue stuff in veins. Usually the formation is steep to vertical, unlike a bedded deposit in which values are sandwiched horizontally. Vein is typically long, deep, and relatively narrow.
Ref: Pryor, 3
viii. The term lode is commonly used synonymously for vein.
ix. The filling of a fissure or fault in a rock, particularly if deposited by aqueous solutions. When metalliferous, it is called by miners a lode; when filled with eruption material, a dike. A bed or shoot of ore parallel with the bedding. Also called blanket deposit.
Ref: Standard, 2
x. A comparatively thin sheet of igneous rock injected into a crevice in rock. When this intrusion is large, it is called a dike.
xi. An irregular, sinuous, igneous injection, or a tabular body of rock formed by deposition from solutions rich in water or other volatile substances.
Ref: Holmes, 2
xii. A mineral body, thin in relation to its other dimensions, which cuts across the bedding and in which the minerals are later than the country rock.
Ref: BS, 11
xiii. Sometimes used for a bed; e.g., a coal seam or a bed of slate.
Ref: BS, 11
xiv. A layer, seam, or narrow irregular body of material different from surrounding formations.
